5.2 Introduction to Rate Law
The initial rates of the reaction represented by the equation below were measured in three separate trials at \(298 \text{ K}\).
\[ 2\text{NO}_2(g) + \text{F}_2(g) \rightarrow 2\text{NO}_2\text{F}(g) \]
Based on the data in the table, which of the following is the correct rate law and overall reaction order for the reaction?
\[ 2\text{NO}_2(g) + \text{F}_2(g) \rightarrow 2\text{NO}_2\text{F}(g) \]
| Trial | \([\text{NO}_2]\ (\text{M})\) | \([\text{F}_2]\ (\text{M})\) | Initial Rate of Formation of \(\text{NO}_2\text{F}\ (\text{M}\cdot\text{s}^{-1})\) |
|---|---|---|---|
| 1 | \(0.10\) | \(0.10\) | \(2.0 \times 10^{-4}\) |
| 2 | \(0.20\) | \(0.10\) | \(4.0 \times 10^{-4}\) |
| 3 | \(0.20\) | \(0.30\) | \(1.2 \times 10^{-3}\) |
Based on the data in the table, which of the following is the correct rate law and overall reaction order for the reaction?
